XhEditor上传

首先导入js文件：

View Code

1   <script type="text/javascript" src="../xheditor/jquery/jquery-1.4.4.min.js"></script>
2     <script type="text/javascript" src="../xheditor/xheditor-1.1.10-zh-cn.min.js"></script>
3     <script type="text/javascript">
4         $(function () {
5             $('#txt_content').xheditor({ cleanPaste: 0, tools: 'mfull', skin: 'nostyle', upLinkUrl: '../upload.aspx', upImgUrl: '../upload.aspx', upFlashUrl: '../upload.aspx', upMediaUrl: '../upload.aspx' });
6         })
7     </script>

新建一个upload.aspx文件（后台代码如下）：

View Code

  2 using System.Collections;
  3 using System.Configuration;
  4 using System.Data;
  5 using System.Web;
  6 using System.Web.Security;

  8 using System.Web.UI.HtmlControls;
  9 using System.Web.UI.WebControls;
 10 using System.Web.UI.WebControls.WebParts;
 11 using System.Text.RegularExpressions;
 12 public partial class upload : System.Web.UI.Page
 13 {
 14     protected void Page_Load(object sender, EventArgs e)

 19         int dirtype = 1;                  // 1:按天存入目录 2:按月存入目录 3:按扩展名存目录  建议使用按天存
 20         int maxattachsize = 419430400;     // 最大上传大小，默认是2M
 21         string upext = "txt,rar,zip,JPG,GIF,jpg,jpeg,bmp,gif,png,swf,wmv,avi,wma,mp3,mid,flv";    // 上传扩展名
 22         int msgtype = 2;                 //返回上传参数的格式：1，只返回url，2，返回参数数组

　　新建一个uploads文件夹即可
